It is cased glass, possibly Czech, but is unmarked. Also note the glaze is shiny and reflective, which make it seem to have patterns on the surface - it does not have any patterning or images. See pictures.
This product would be a great fit for those looking for a uniquely crafted, tall art glass vase featuring iridescent, lavender colored glass, perfect for displaying prized plants or serving as an eye-catching centerpiece.
